Euro 2016 final – why did moths invade the pitch?
Where did all those moths come from that interrupted the France-Portugal Euro 2016 final in the Stade de France?
Impressive numbers of moths in the Stade de France provided light relief during a pretty dull finale to Euro 2016. “The moths were great but the football was lousy,” agrees Richard Fox, an expert at Butterfly Conservation.
One moth even landed on the face of stricken Portuguese superstar Cristiano Ronaldo – a gift for headline writers around the world. But what were the moths, and why were so many of them in central Paris?
“These were Silver Y moths,” says Fox. “They are a migratory species, just like swallows, and they move north through the continent in large numbers in spring and summer as the weather warms. Then they fly south again to winter in warmer areas.”
It is a multi-generational migration, as with painted lady butterflies in Europe and monarch butterflies in North America. “The adult moths move north in spring, then stop to breed,” explains Fox. “Then when their caterpillars have grown up and developed into moths, they continue the journey north, before it is their turn to stop and breed, and so on. It’s a bit like a relay race.”
‘There is obviously a mass movement of Silver Y moths going on in France at the moment,” Fox adds. “They would have been attracted to the stadium lights – like a massive moth trap.”
Here in Britain sightings of Silver Y moths have been on the increase since early July. The migratory species is a common summer and autumn visitor to gardens and the countryside, and will even – as the Portugal–France match demonstrates – flock to city centres. The moths are often disturbed by day from their resting place among grass or vegetation.
The Silver Y moth is also one of the species included in the Big Butterfly Count, organised by Butterfly Conservation. In 2016 this annual citizen-science event runs from 15 July to 7 August.
“Given the big numbers of Silver Ys seen recently in France, it will be fascinating to see how many of the moths are reported in Britain during the count,” Fox says. “They may well be crossing the Channel any time now.”
